What is 12.25 percent of 15.5 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 15.5 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 15.5 is 100%, so we can write it down as 15.5=100%.
4. We know, that x is 12.25% of the output value, so we can write it down as x=12.25%.
5. Now we have two simple equations:
1) 15.5=100%
2) x=12.25%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
15.5/x=100%/12.25%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 12.25% of 15.5

15.5/x=100/12.25
(15.5/x)*x=(100/12.25)*x       - we multiply both sides of the equation by x
15.5=8.1632653061224*x       - we divide both sides of the equation by (8.1632653061224) to get x
15.5/8.1632653061224=x
1.89875=x
x=1.89875

now we have:
12.25% of 15.5=1.89875
